Description

The invention relates to a device for recording of liquids, one from a side wall limited interior space, a floor as well as a Has mouth section and with a handle is provided with a handle base in the area of Mouth section is supported.

Such devices are typically manufactured by Blow molding starting from previously tempered Preforms made. The attachment of a handle relieved especially with larger devices manual handling and transport.

In the case of container formation due to blowing pressure become preforms from a thermoplastic Material, for example preforms made of PET (Polyethylene terephthalate), inside a blowing module fed to different processing stations. Such a blowing module typically has one Heating device and a blowing device on, in whose area the pre-tempered preform through Biaxial orientation to a container expands becomes. The expansion takes place with the help of compressed air, which are introduced into the preform to be expanded becomes. The procedural process at a such expansion of the preform is in the DE-OS 43 40 291 explains.

Within the blow module, the preforms can as well the blown containers with the help of different Handling devices are transported. Known is for example the use of transport mandrels, onto which the preforms are placed. The Moldings can also be used with others Carriers are handled. The use of Gripping pliers for handling preforms described for example in FR-OS 27 20 679. On Expanding mandrel, which is used for holding in a mouth area of the preform is insertable in the WO 95 33 616 explains.

The shaping of preforms already explained Containers are made on the one hand with the so-called Two-step process in which the preforms first manufactured in an injection molding process, then temporarily stored and only later conditioned in terms of their temperature and too inflated in a container. On the other hand such a transformation in the so-called One-step process in which the preforms immediately after their injection molding manufacture and sufficient consolidation tempered and then inflated.

Common to all processes is that the preform is a has a much smaller shape than the containers to be manufactured. The preform is therefore pressurized air inside the blowing station, to transform it into the container to be manufactured. at this inflation takes place in addition to Reduction of the wall thickness by the Surface enlargement an orientation of the Material. This means that the thin wall of the Container has a very high dimensional stability that the container for a variety of uses makes suitable.

To carry out the blowing process different methods known. For one thing it is possible to use a uniform blowing pressure which is introduced into the preform to be inflated and after sufficient shaping from the finished container against an ambient pressure is drained. It’s also known first a pre-expansion of the preform, the this already relatively far to the shape of the approximates the container to be manufactured, with a lower pressure, and only the expression the finer contour of the container with a higher one Pressure. This procedure is also followed the production of the container against one Ambient pressure is vented.

The currently used handles for containers Absorption of liquids and especially for Blown bottles can not meet all requirements meet that both in a simple and inexpensive Manufacturing, easy handling at a Use by the end user as well as to a high resilience at the same time.

The object of the present invention is a Device of the type mentioned in the introduction construct that high functionality at the same time simple manufacturability is achieved.

This object is achieved in that the handle in the area of one facing away from the handle base Handle end has a bracket profile, which by a Counter profile of the side wall is added that the Counter profile through blow molding in the area of Sidewall is formed and that Bracket profile in the already formed counter profile can be introduced.

The combination of those in the area of the mouth section held handle base with the in the area of Counter profile recorded bracket profile provides a also withstands larger loads Handle ready. Through the possibility of introduction of the mounting profile in the counter profile after one it is blow molding manufacture of the device possible both a previous production step an injection molding manufacture of a Preform as well as the following Blow molding production step with relative low effort and therefore inexpensive and with a high throughput rate per unit time.

For the reliable absorption of weight forces suggested that the bracket profile towards a handle longitudinal axis form-fitting from the counter profile is included.

A typical realization is that the Positive locking by changing the cross section of the Handle and a corresponding contour of the Counter profile is realized.

In particular, it is thought that the positive connection by profiling a width of the handle across to the handle longitudinal axis is realized.

To ensure resisting loads Fixing the handle relative to the side wall suggested that the handle form-fitting in a radial direction is supported by the counter profile.

A simple implementation option is that the positive connection by a cross-sectional profile of the Handle and an adapted contour of the Counter profile is realized.

Easy handling with a blow molding Manufacture of the device from an injection molded Preform is achieved in that the handle base from a mounting ring in the area of Mouth section is fixed.

A transfer of forces between the handle and the Mouth section is supported in that the Retaining ring in the area of the Mouth section is fixed.

In particular, it is thought that the positive connection through a profile similar to a bayonet catch is realized.

This makes a compact embodiment provided that the handle base integrally with the Mouth section is formed.

In particular, it is contemplated that the handle base in is formed on an environment of a support ring.

To avoid disabilities in a blow molding manufacture of the device suggested that the handle end via a hinge is arranged pivotably relative to the handle base. Due to the pivotable arrangement, it is possible that the handle end while performing the Any position relative to the manufacturing process Handle base can take to thereby handling to simplify.

In terms of manufacturing technology, it turns out to be special advantageous that the hinge as a film hinge is trained.

A transfer of forces from the end of the handle to Handle base is supported in that the handle base in the area of its extension facing the joint Has boundary surface that is inclined to a Longitudinal preform axis runs.

Another way of realizing a Form fit between the bracket profile and the Counter profile is that the handle end in Area of its extension facing away from the handle base is hook-like.

This creates an aesthetic appearance supports that an outer surface of the handle end in Area of the bracket profile essentially flat with a surface of the side wall.

To allow a combination of different Material properties suggest that the handle from a different from the side wall Material is formed.

In particular, it is also contemplated that the handle in Area of the handle base with the material of the Mouth section is overmolded.

Carrying out separate manufacturing steps at injection molding manufacturing of the preform avoided by the. Handle and the Mouth section in a common injection molding process are made.

A disadvantageously large amount of heat prefabricated handle in the injection molding This will produce the rest of the preform avoided that the handle as an insert in the Execution of the injection molding process at least in areas and at least temporarily by one Cooling cassette is added.

The device for holding liquids can be manufactured, for example, when the one-step process is implemented. The basic structure of such a single-stage device using an injection molding module ( 1 ) and a blowing module ( 2 ) is shown in Fig. 1.

The embodiment of a single-stage device for container forming shown in FIG. 1 has an injection molding module ( 1 ) and a blow module ( 2 ), which are connected to one another by a transfer device ( 3 ). The injection molding module ( 1 ) is equipped with an extruder ( 4 ) and an injection mold ( 5 ), in the area of which a plurality of cavities ( 6 ) for the production of preforms ( 7 ), not shown in FIG. 1, are arranged.

The blow module ( 2 ) is provided with a plurality of mounting elements ( 8 ) which can be transported along a closed circulation path ( 9 ). The holding elements ( 8 ) are fed to a blowing station ( 10 ), in the area of which the preforms ( 7 ) are deformed relative to one another into containers ( 11 ), not shown. A distance from the longitudinal axes ( 12 ) of the preforms ( 7 ) relative to one another is greater in the area of the blowing station ( 10 ) than in at least one other area of the circulation path ( 9 ).

In order to carry out the change in distance of the longitudinal axes ( 12 ) of the preforms ( 7 ), a distance between the holding elements ( 8 ) is changed relative to one another. This change in distance can be carried out with the aid of a distance modifier ( 13 ), which according to the embodiment in FIG. 1 is provided with a spiral-like profile ( 14 ). In the embodiment shown, the spiral profile ( 14 ) is designed as a groove in a shaft ( 15 ) which is connected to a drive ( 16 ) for specifying a rotational movement. The drive ( 16 ) can be coupled to the shaft ( 15 ) via a gear ( 17 ).

When using a shaft ( 15 ) with a groove-like profile ( 14 ), the holding elements ( 8 ) are advantageously provided with guide elements ( 18 ) which engage in the profile ( 14 ). The guide elements ( 18 ) can be formed, for example, from laterally projecting bolts which carry cam rollers ( 19 ).

The combination of the injection molding module ( 1 ), the blowing module ( 2 ) and the transfer device ( 3 ) provides a so-called one-step device for blow molding containers ( 11 ), in which the preforms ( 7 ) from the injection molding module ( 1 ) to the blowing module ( 2 ) be transferred at a temperature that is above the ambient temperature. It is therefore not necessary in the area of the blow module to heat the preforms ( 7 ) from an ambient temperature to the blow temperature, but only a suitable temperature modification or temperature profile is required in the area of a temperature control section ( 20 ). For this purpose, the temperature control section ( 20 ) has heating devices ( 21 ) which can be equipped, for example, with infrared radiators. To improve the utilization of the applied heating energy, reflectors ( 22 ) are used. In the embodiment shown, the reflectors ( 22 ) have a reflector profile ( 23 ) which is adapted to the external design of the preforms ( 7 ). The reflectors ( 22 ) can be positioned transversely to the circulation path ( 9 ) in order to support the closest possible arrangement on the preforms ( 7 ).

The support elements ( 8 ) are transported along the circulation route ( 9 ) in cycles with successive standstill phases and transport phases. The function of the transfer device ( 3 ), the positioning of the reflectors ( 22 ) and the rotational movement of the distance modifier ( 13 ) are adapted to the respective movement cycle. A conveyor of the holding elements (8) along the circulation path (9) can be effected for example by means of a driven sprocket (24) having a profile (25) for acting on the holding elements (8) and preferably in the region of a deflection of the circulation path (9) is arranged.

The cycle operation of the blow module ( 2 ) is controlled in such a way that a larger number of preforms ( 7 ) can be produced in the area of the injection molding module ( 1 ) than are subsequently simultaneously formed into containers ( 11 ) in the area of the blow module ( 2 ). For example, in the variant shown, the idea is to produce ten preforms ( 7 ) simultaneously in the area of the injection molding module ( 1 ) and to produce two containers ( 11 ) in the area of the blowing station ( 10 ) at the same time.

Another variant consists in producing five preforms ( 7 ) simultaneously in the area of the injection molding module ( 1 ) and simultaneously producing a container ( 11 ) in the area of the blowing station ( 10 ).

Fig. 2 illustrates in a side view the structure of the transfer device ( 3 ). In particular, it can also be seen that the injection mold ( 5 ) is formed from a cavity block ( 26 ) and from injection molding cores ( 27 ) which can be positioned relative to the cavity block ( 26 ) by a lifting device ( 28 ). After a sufficient thermal solidification of the preforms ( 7 ) within the injection mold ( 5 ), the preforms ( 7 ) are raised together with the injection molding cores ( 27 ) and a support element ( 29 ) of the transfer device ( 2 ) can be moved into the area of the injection molding module ( 1 ) retract. The preforms ( 7 ) are then inserted into transport recesses ( 30 ) in the support element ( 29 ). This takes place, if necessary, after opening the mouth molds ( 31 ) and to facilitate stripping off the injection-molded cores ( 27 ) with compressed air support or using suitable stripping or ejection devices.

The support element ( 29 ) is carried by an adjusting device ( 32 ) which is arranged displaceably along a guide ( 33 ). After the support element ( 29 ) has been moved, the support element ( 29 ) is raised by the adjusting device ( 32 ) so that the preforms ( 7 ) can be acted upon by the mounting elements ( 8 ).

The support elements ( 8 ) are guided along the circulation path ( 9 ) by rails ( 34 ). In the area of the blowing station ( 10 ), a connecting piston ( 35 ) can be lowered, through which a pressurized medium for expanding the preforms ( 7 ) can be passed through the holding element ( 8 ) into the preforms ( 7 ).

To illustrate the manufacture of preforms ( 7 ) which are provided with a prefabricated handle ( 61 ) during the execution of the injection molding process, a handling device ( 83 ) is shown in FIG. 2 which is used to insert such prefabricated handles ( 61 ) into the injection mold ( 5 ) can be used.

Fig. 3 shows a side view of the blowing station ( 10 ). The blowing station ( 10 ) is provided with mold carriers ( 36 , 37 ) which each hold blow mold segments ( 38 , 39 ). The mold carriers ( 36 , 37 ) together with the blow mold segments ( 38 , 39 ) can be adjusted transversely to the circulation path ( 9 ) in order to be able to carry out opening and closing movements. In the embodiment shown, the mold carriers ( 36 , 37 ) are positioned with the aid of pivoting levers ( 40 ) which are pivotably mounted in the region of a base plate ( 41 ). The pivot levers ( 40 ) have main bearings ( 42 ) for connection to the base plate ( 41 ). A connection to the mold carriers ( 36 , 37 ) takes place via swivel joints ( 43 ), a connection to a positioning element ( 44 ) takes place via swivel joints ( 45 ).

The positioning element ( 44 ) can be adjusted in the vertical direction along a guide ( 46 ). The adjustment can take place, for example, with the aid of a threaded rod ( 47 ) which is set in rotation by a drive ( 48 ). When the positioning element ( 44 ) is raised, the blowing station ( 10 ) is opened, and when the positioning element ( 44 ) is lowered, the blowing station closes.

From Fig. 3 it can also be seen that a lifting device ( 49 ) is used for positioning the connecting piston ( 35 ), which has a drive ( 50 ). The lifting device ( 49 ) has guide elements ( 51 ) for a transport carriage ( 52 ) which holds the connecting piston ( 35 ). The adjustment movement can be transmitted, for example, via a drive belt ( 53 ).

Fig. 4 shows schematically within the blowing station ( 10 ) in addition to the blown container ( 11 ) in dashed lines the preform ( 7 ) and a developing container bladder ( 54 ). The preform ( 7 ) or the container ( 11 ) can be held within the blow molding station ( 10 ) by a threaded insert ( 55 ) and a stretching rod ( 56 ) is used to stretch the preform ( 7 ). The threaded insert ( 55 ) holds a mouth section ( 57 ) of the preform ( 7 ) and the stretching rod ( 56 ) exerts pressure on a bottom ( 58 ) of the preform ( 7 ) while the stretching process is being carried out during the feed movement. The blow mold ( 10 ) can be provided with a base insert ( 60 ) in order to enable the shape of a container base ( 59 ) with contour undercuts.

Different thermoplastic materials can be used Plastics are used. Are operational for example PET, PEN or PP.

The preform ( 7 ) expands during the orientation process by supplying compressed air. The compressed air supply is divided into a pre-blowing phase, in which gas, for example compressed air, is supplied at a low pressure level and into a subsequent main blowing phase, in which gas is supplied at a higher pressure level. Compressed air with a pressure in the interval from 10 bar to 25 bar is typically used during the pre-blowing phase and compressed air with a pressure in the interval from 25 bar to 40 bar is fed in during the main blowing phase.

Fig. 5 shows a blown container ( 11 ) which is provided with a handle ( 61 ). The handle ( 61 ) has a handle base ( 62 ) which is held in the region of the mouth section ( 57 ) of the container ( 11 ). In the embodiment shown, the handle base ( 62 ) is held by means of a holding ring ( 63 ) which surrounds the mouth section ( 57 ). In particular, it is contemplated to attach the retaining ring ( 63 ) in a form-fitting manner in the region of the mouth section ( 57 ). This can be done, for example, by screwing an internal thread of the mounting ring ( 63 ) onto an external thread of the mouth section ( 57 ) or by profiling in accordance with a bayonet catch.

In the area of a handle end ( 64 ) facing away from the handle base ( 62 ), the handle ( 61 ) has a mounting profile ( 65 ) which is received by a counter profile ( 66 ) of the container ( 11 ). The counter profile ( 66 ) is arranged in the region of a side wall ( 67 ) of the container ( 11 ). In the embodiment shown, the handle end ( 64 ) consists of a handle cap ( 68 ) and a handle bar ( 69 ) which is slimmer relative to the handle tip ( 68 ). This provides a positive connection between the mounting profile ( 65 ) and the counter profile ( 66 ) in the direction of a longitudinal handle direction ( 70 ) running from the handle end ( 64 ) to the handle base ( 62 ), which prevents the handle ( 61 ) from moving in the direction of the handle longitudinal axis ( 70 ) is pulled out of the counter profile ( 66 ). The handle ( 61 ) is thereby positively connected to the container ( 11 ) both in the area of the mounting ring ( 63 ) and in the area of the handle end ( 64 ), so that a filled container ( 11 ) is also carried using the handle ( 61 ) can be.

Fig. 6 shows an enlarged cross-sectional view in the region of the holder of the handle bar ( 69 ) by the counter profile ( 66 ). In particular, it can be seen that the counter profile ( 66 ) widens in the direction of an interior ( 71 ) of the container ( 11 ) and that the handle web ( 69 ) also has a cross-sectional profile that widens in the direction of the interior ( 71 ). This also provides a positive connection in a radial direction of the container ( 11 ), which prevents the handle ( 61 ) from being unintentionally pulled out of the counter-profile ( 66 ) in a radial direction.

FIG. 7 illustrates the arrangement according to FIG. 5 in a perspective illustration. In particular, it can be seen that an outer surface ( 72 ) of the handle ( 61 ) runs essentially flat to a surface ( 73 ) of the side wall ( 67 ). In addition, it can be seen how the positive connection between the handle end ( 64 ) and the side wall ( 67 ) is realized by the engagement of the mounting profile ( 65 ) in the counter profile ( 66 ).

Fig. 8 shows an embodiment with a modified configuration of the handle end (64). In this embodiment there is a modified design of the mounting profile ( 65 ) and the counter profile ( 66 ). The modified design means that no change in cross section of the handle ( 61 ) can be seen from the outside. The profiling is rather realized in an area that is not visible from the outside. This design means that a very harmonious transition between the outer surface ( 72 ) of the handle ( 61 ) and the surface ( 73 ) of the side wall ( 67 ) is realized.

Fig. 9 shows a preform ( 7 ) for producing a container ( 11 ). The handle (61) of the preform (7) has in the region of a grip end (64) has a design which corresponds to the not visible in Fig. 8 design of the handle end (64). Compared to the embodiment in Fig. 8, however, the handle base ( 62 ) is held differently. From Fig. 9 it can be seen in particular that the preform ( 7 ) has a support ring ( 74 ) which is located in a region of the mouth section ( 57 ) which is arranged facing a neck ( 75 ) of the preform ( 7 ). The handle base ( 62 ) is preferably injection molded onto the support ring ( 74 ) or at least part of the mouth section ( 57 ) in the vicinity of the support ring ( 74 ). It is also possible to produce the handle base ( 62 ) together with the preform ( 7 ) in a common injection molding process.

The handle end ( 64 ) has a radial web ( 76 ) which is transferred into a hook web ( 77 ). The hook web ( 77 ) extends essentially parallel and at a distance from a main segment ( 78 ) of the handle end ( 64 ). Due to the contour of the main segment ( 78 ) of the radial web ( 76 ) and the hook web ( 77 ), the handle ( 61 ) is provided with a mounting profile ( 65 ), which has both a radial fixation and a fixation in a longitudinal direction of the blown container ( 11 ) enables.

Fig. 9 also illustrates that the handle base ( 62 ) is pivotally connected to the handle end ( 64 ) via a joint ( 79 ). In particular, it is contemplated to design the joint ( 79 ) as a film hinge, which is injection molded in one piece with the handle base ( 62 ) and the handle end ( 64 ). Injection molding, temperature control for carrying out the blowing process and the actual blow molding are carried out with the spatial orientation of the handle ( 61 ) shown in FIG. 9. This avoids in particular complex and therefore expensive special handling devices.

FIG. 10 shows a container ( 11 ) which was produced from the preform ( 7 ) according to FIG. 9. After the container ( 11 ) had been blown, the handle end ( 64 ) was pivoted around the joint ( 79 ) so that the mounting profile ( 65 ) could be inserted into the counter profile ( 66 ). Due to the respective contour profiles, the handle end ( 64 ) is fixed in the area of the counter-profile ( 66 ), so that a load-bearing arrangement of the handle ( 61 ) is realized.

FIG. 11 illustrates another perspective illustration of the preform ( 7 ) according to FIG. 9. Here, in particular, the design of the handle ( 61 ) can be seen in the vicinity of the joint ( 79 ). A boundary surface ( 81 ) of the handle base ( 62 ) is inclined relative to a preform longitudinal axis ( 80 ). A boundary surface ( 82 ) of the handle end ( 64 ) facing the boundary surface ( 81 ) has an inclination corresponding to the boundary surface ( 81 ). The corresponding inclinations of the boundary surfaces ( 81 , 82 ) mean that, in the pivoted position shown in FIG. 12, the handle end ( 64 ) is supported vertically via the boundary surface ( 82 ) in the region of the boundary surface ( 81 ) in a working position. In this way, weight forces can be better absorbed via the film hinge.

Fig. 13 illustrates in a made once the design of a container (11) from the preforms shown in Fig. 11 and Fig. 12 compared to FIG. 10 modified perspective view. It can be seen in particular that the contour of the handle ( 61 ) is integrated very harmoniously into the contour of the rest of the container ( 11 ).
